First of all, thanks for being cool and giving some details. Sometimes people take it the wrong way
Well, the first good news is that there are members in this forum using Linux on your laptop, as you can see here
, he/she is having a problem with the sound card.
I have to agree with oskar as well. Try the alternate CD. Ubuntu was cooler when we had two disks: One for Live and one for the actual installation. But I understand that this way they are saving a lot of bandwidth and money on ship-it as well.
But back to your problem: If trying with the alternate CD still fails, boot up again. On the first screen, you are given a few options, like running a memtest and checking the CD's integrity. I'd recommend doing both. If you are still unlucky, try asking the member in that thread I linked if he/she had encounter any problems installing Linux. Who knows, maybe he/she had used some commands to get it to install.
Keep as posted please. I will google a bit more and see what I can dig.
Best of luck!
